A new method for the determination of cholesterol in serum is being developed in which
the rate of depletion of oxygen is measured with an oxygen electrode upon reaction of the
cholesterol with oxygen, when catalyzed by the enzyme cholesterol oxidase.
a. Use Q-test and Grubb’s Test in determining if the extreme values (higher and
lower) are outliers.
b. Compute for the value of mean, standard deviation, and RSD for the data set (after rejecting
any outliers from the Grubb’s test)

 
53. A new method for the determination of cholesterol in serum is being developed in which the rate
of depletion of oxygen is measured with an oxygen electrode upon reaction of the cholesterol with
oxygen, when catalyzed by the enzyme cholesterol oxidase. The results for several samples are
compared with those of the standard Lieberman colorimetric method. From the following data,
determine by the t-test if there is a statistically significant difference between the two methods
and calculate the correlation coefficient. Assume the two methods have similar precisions.
